Error when changing page URL on fresh install

Hi,

I just installed kirby and started to use it. Whenever I want to change the URL of the page “photography” to anything else, the panel crashes and I am redirected to the following error message:

{"status":"error","message":"Unauthenticated","code":401,"key":"error.auth","details":[]}

It happens independently whether I just shorten it to “photo” or change it to something completely different. I can restore the panel access by changing the folder name in content/ back to 1_photography.

Technical data

kirby: 4.2.0
php: 8.2.19

The albums section (site/blueprints/sections/albums.yml), sets the photography page as parent, so you would need to change that to the new page slug as well.
